胸部X射线(CXR)摄影可用作非COVID-19肺炎患者的一线分诊过程。然而,COVID-19和其他感染引起的肺炎的CXR图像特征之间的相似性使得放射科医生的鉴别诊断具有挑战性。我们假设基于机器学习的分类器可以可靠地区分COVID-19患者的CXR图像与其他形式的肺炎。我们使用降维方法来生成CXR图像的一组最佳特征,以构建一个高效的机器学习分类器,该分类器可以以高准确度和灵敏度区分COVID-19病例和非COVID-19病例。通过使用整个CXR图像的全局特征,我们使用相对较小的CXR图像数据集成功地实现了我们的分类器。我们建议我们的COVID分类器可以与其他测试结合使用,通过快速分类非COVID-19病例来优化医院资源的分配。
Chest-X ray (CXR) radiography can be used as a first-line triage process for non-COVID-19 patients with pneumonia. However, the similarity between features of CXR images of COVID-19 and pneumonia caused by other infections makes the differential diagnosis by radiologists challenging. We hypothesized that machine learning-based classifiers can reliably distinguish the CXR images of COVID-19 patients from other forms of pneumonia. We used a dimensionality reduction method to generate a set of optimal features of CXR images to build an efficient machine learning classifier that can distinguish COVID-19 cases from non-COVID-19 cases with high accuracy and sensitivity. By using global features of the whole CXR images, we successfully implemented our classifier using a relatively small dataset of CXR images. We propose that our COVID-Classifier can be used in conjunction with other tests for optimal allocation of hospital resources by rapid triage of non-COVID-19 cases.
